All about Primus Line Kevlar liners for trenchless rehabilitation

At hebs Flowtech we are able to offer Primus Line Kevlar liners for trenchless rehabilitation of pressure pipes across a range of different industrial applications.

Primus Line Kevlar liners overcome some of the common problems faced with industrial pressure pipes, for example:

  • Weaknesses in bends and corners.
  • Loss of strength due to age and corrosion.
  • Sensitive installation environments.
  • Long length pipeline installations.
  • High hydraulic capacity demands.

This is all thanks to the Kevlar construction of the pipes, which strengthens the structure while allowing the walls of the pipe to be much thinner – and this in turn means the inner diameter of the pipe can be bigger, supporting higher capacity and flow rates.


Construction of Primus Line Kevlar liners

Primus Line Kevlar liners have three distinct layers that combine to create a flexible but incredibly strong cross-section:

  • An outer layer of abrasion-resistant polyurethane known as the sheath.
  • A load-bearing Kevlar layer (or double layer) of seamless woven aramid fibres.
  • A media-specific inner layer of polyurethane or thermoplastic polyurethane (TPU).

The single or double Kevlar layer hidden between the polyurethane layers gives the pipe its extremely high load-bearing strength, while allowing the total construction of the pipe walls to be much thinner than if solid high-density polyethylene or a similar material were to be used.

In turn, this maximises flow capacity but also means that these thinner pipe walls are more flexible, and Primus Line can negotiate around bends of up to 45 degrees, with a series of specially designed connectors to navigate around any even tighter corners as required.


Trenchless rehabilitation with Primus Line Kevlar liners

At hebs Flowtech we can install Primus Line Kevlar liners as part of trenchless rehabilitation work, which means less disruption, less delay and less cost to reinstate disturbed ground.

This again is due in part to the flexibility and strength of Primus Line, which can be inserted into the existing pipework in need of trenchless rehabilitation, but does not need to be bonded to the inner surface of the pipe.

Because of their excellent load-bearing strength, Primus Line liners are self-supporting and able to ‘float’ inside the existing pipe, while their thin walls mean only a minimal reduction in the inner diameter of the pipeline.

Blue light patch lining cures in place for faster repairs

Blue light patch lining technology is at the cutting edge of pipe repairs, offering faster, more convenient and less disruptive patch repairs for broken pipes.

Also known as cured-in-place pipe, or CIPP, this innovative drain and sewer lining technology uses ultraviolet light – off the blue end of the visible light spectrum – to activate resin patches once they are in place.

This means the resin can be positioned accurately and only then is the curing process triggered, so that the result is extremely reliable and achieved as quickly and cleanly as possible.


Working on blue light patch lining in the north-west

We are proud to be the preferred drainage contractor for many organisations and projects in the north-west, and we also welcome direct enquiries from customers new and old.

Together our ever-growing client base allows us to work on blue light patch lining in the north-west’s towns and cities, across Merseyside, Greater Manchester, Lancashire and beyond, wherever this innovative technology is needed.

It’s also the first time a drainage contractor in the north-west has offered CIPP curing to the facilities management and private sectors, courtesy of hebs Flowtech, our specialist drainage and pipeline services provider.


More benefits of blue light patch lining

The main benefits of blue light patch lining are its ease of use, fast application and curing times, and its availability even in confined areas, but there are many more advantages to using this cutting-edge technology:

  • Position of the blue/UV lights gives excellent control over curing.
  • Multiple patches can be applied quickly and with excellent results.
  • Low energy consumption means no large generators needed.
  • Less landscape disruption means less environmental impact.
  • Easier to make land ready for future use with less digging needed.

If you’re not sure if UV patch lining is right for your project, that’s fine too – just ask and we will be happy to advise on suitability and, if CIPP curing is not suitable for any reason, we can recommend an alternative instead.

Building buildings: New construction from start to finish

When we talk about ‘building’ we mean the process of new construction, and the finished product – the newly built premises that you can then begin to use.

It’s no surprise that the same word applies to both parts of the new-build construction process, as it’s important to design new buildings to suit their purpose and to deliver them to a high standard.

The best architect’s plans can be undermined by poor execution, and the best builders cannot construct premises for one purpose if they were designed for something completely different.

That’s why at hebs group, we are proud to offer new-build construction services that start with your vision for what you want your premises to achieve, and end with delivering on that purpose to the highest of standards.

By adopting this holistic, start-to-finish approach, we are able time and time again to build buildings that meet the needs of our clients while incorporating all of the benefits of modern design methods and materials.


Industry and environment

We also understand that new-build construction is increasingly about delivering more than just the fabric of the building – there’s an ever-growing focus on its environmental impact and industry-specific legislation on issues like carbon footprint and energy management.

By taking all these factors into consideration from the start of the design and construction process, we can make sure you receive premises that make the best use of current innovations in building management and energy efficiency.

Smart building design also means future maintenance to the building fabric, roofing, HVAC and other services is easier and more cost-effective, so you can continue to install new technologies and upgrade your existing building infrastructure in the years to come.


A long and happy life

At hebs group we deliver new-build construction that is designed to withstand the test of time, while also being upgraded to benefit from new environmental technologies.

We know that many of these buildings will stand for decades, and there’s a huge sense of pride associated with that for anyone who works in new-build construction.

For existing premises, we can refurbish, refit and retrofit as appropriate to give you fresh interiors that are comfortable and welcoming to work in or otherwise occupy.

And on new-build construction we will always go the extra mile to produce a property that is not just fit for purpose, but really delivers on your dream of what you hoped to achieve from the first napkin sketch, to the ribbon-cutting ceremony and beyond.

Rapid rise in renewable energy installations in 2018

A substantial increase in renewable energy installations coming online in 2018 meant that for the first time, the majority of electricity generated in the UK came from low-carbon sources like solar, wind, hydro and nuclear.

Figures from climate and energy news provider Carbon Brief show coal-fired power plants continued to close with output down 25% in 2018, gas generation fell by 4% and nuclear – considered a low-carbon energy source – was down 7% over the year.

In contrast, offshore windfarm capacity almost doubled in a single year, taking total wind power output to 58 TWh, solar power installations were up 11% at total capacity of 13 TWh and biomass generation rose 13% to 36 TWh, with hydro power contributing a further 5 TWh to low-carbon electricity capacity.

Fossil fuels now account for just 46% of UK electricity generation – the lowest percentage on record – while low-carbon energy sources accounted for 53% of output in 2018 and renewable energy installations in particular totalled about a third of all UK energy capacity.

At hebs Group we have seen this trend first-hand, in our work to supply and install cutting-edge renewable energy technologies such as solar panels and ground source heat pumps to support businesses in reducing emissions, lowering energy bills and protecting the environment.


How renewable energy installations are helping meet climate goals

The figures show that the increase in renewable energy capacity in the UK since 2005 is almost the same as the total amount of energy saved through measures like the move towards low-energy lightbulbs and more energy-efficient vacuum cleaners and kitchen appliances.

Combining the 103 TWh of energy saved through more efficient appliances and the 95 TWh of additional renewable energy installations, annual CO2 emissions are much lower than they otherwise would be – without these factors, emissions would be around 20% higher for gas-powered stations and 50% higher using coal.

“Lowering electricity use is not an end in itself, given the useful services it provides,” Carbon Brief concludes. “But energy efficiency and renewable energy are both key elements of most pathways to meeting UK and global climate goals.”

In response to the publication of the figures, Lawrence Slade, chief executive of the energy industry trade organisation Energy UK, urged these trends to continue with greater installations of wind and solar power to support the UK’s decarbonisation efforts across business and residential premises alike.

He added: “We are calling for the government to roll out a National Energy Efficiency Programme across the UK for domestic and non-domestic premises.”

We will continue to work hard to add to the total capacity of renewable energy generation for business premises across the UK, as well as providing essential electrical maintenance services to keep existing renewable energy installations running efficiently and contributing as much as possible to low-carbon energy output in the UK.

What does 2019 hold for UK construction?

It’s always difficult to predict how the UK construction industry will fare over the course of a full 12 months, but 2019 in particular will be hard to anticipate, with the final arrangements for Britain’s withdrawal from the European Union still to be made.

With that in mind, what can we be sure of for UK construction in 2019 – regardless of the final decisions that are made with respect to Brexit?


ACM Cladding

Aluminium Composite Material cladding – more commonly known simply as ACM cladding – was banned by the UK government following safety tests carried out after the Grenfell Tower fire.

In late 2018 the government announced that it is giving local authorities powers to remove ACM cladding from privately owned buildings over 18 metres tall, and that building owners will be expected to reimburse the costs.

New buildings over that height must not use ACM cladding – not only including residential buildings, but also student accommodation, boarding school dormitories, residential care premises and hospitals.

The news represents an important step in terms of safety but could be costly for building owners, who may wish to look into having any current ACM cladding removed as a priority, before the local authority carries out the work.


Contractor prompt payment initiative

The government has also announced plans starting from autumn 2019 to award public sector contracts only to contractors who pay their suppliers on time.

Cabinet Office Minister Oliver Dowden said: “From 2019, if government contractors are late with supplier payments, they could stop winning public contracts altogether until they clean up their act.”

It’s part of the government’s broader commitments to levelling the public sector playing field for SMEs, which include a target to pay 90% of undisputed invoices within five days, and for one in every three pounds of government contract spending to be placed with SMEs by 2022.


Modular construction and MMC

Modern methods of construction (MMC) including off-site modular construction are on the rise, allowing construction firms to build new properties as individual modules off-site, which are then delivered directly into their final position.

Back in 2017, the government’s Housing White Paper pledged to create more opportunities in modular construction, as Sajid Javid promised that “British companies can become world leaders in this exciting and effective area”.

At the end of 2018 the government’s housing agency Homes England elected to use modular MMC in the construction of its new office at the heart of an 8,500-property development in Northstowe.

With environmental pressures leading to more construction on brownfield sites and in densely populated areas, modular construction offers a way to carry out much of the work off-site, minimising disruption and noise during the final installation – and will be a trend to watch throughout the coming year and beyond.

Commercial premises refurbishment improves aesthetics and adds value

At hebs Group we offer reactive maintenance to restore commercial premises to full working order quickly following a disaster like a flood or roof collapse – but planned commercial premises refurbishment can add considerable value at any time too.

You don’t have to wait for the roof to fall in before sprucing up your commercial premises, and there’s no better time than at the start of the year when you may have had tenants move out at the end of December, or noticed signs of wear and tear during the less calm weather of the winter months.

Commercial premises refurbishment is an opportunity to have a full spring clean of your property, removing any damaged stud walls or water-stained suspended ceilings and replacing them with modern materials for a fresh, new and inviting look.


Why renovate commercial premises?

It’s not just about making your commercial premises look better – it’s also about maximising their rental value and their appeal to prospective tenants, high-calibre employees, investors, customers and clients.

Modern, well-maintained commercial premises with attractive interiors send out the right message about who you are as a brand, boost productivity from your workforce by giving them a more pleasant place to work, and can even help to maintain healthier employees compared with damp or cold interiors.

This all means that when you renovate commercial premises you are making an investment that will reap returns in the years to come, whether by reducing employee absenteeism, boosting sales and investment, or just by giving you a workplace that you can use effectively.


Our commercial premises refurbishment services

We offer a range of commercial premises refurbishment services – our construction background means we can build extensions and arrange new infrastructure like fibre networks if required too.

Even within the existing building footprint, we can make significant improvements including:

  • Reconfigured room layouts and optimised stud walls.
  • Energy-saving heating, ventilation and air conditioning.
  • Smart lighting and building control systems.

We work across all sectors, from commercial and office, to industrial and infrastructure, and in both the private and public sectors, with a good appreciation of the different pressures faced in each.

To find out more about how hebs Group can bring your commercial premises up to scratch as the new year gets underway, contact us on 0151 236 0707 or email and a member of our team will be happy to help.

The hebs Group awarded conservation award

We’re pleased to announce that we have been awarded a Salisbury Civic Society conservation award for our work on new classrooms and hall extension at Downton CE Primary School.  

The school, originally late Victorian, had already been extended once and the challenge was to match the existing extension style whilst maximising space and creating an open and modern learning facility.  

The work at the school was given a commendation and the Society report noted that “the general impression was that a calming and supporting environment had been created, which would be beneficial to staff and parents as well as children.”  The report went onto say that “the overall impression was of a very worthwhile project, designed and carried out with great care.”

Paul Bolland, managing director of The hebs Group, said of the award: “We’re extremely proud of our work on Downton CE Primary School and honoured to have had this work recognised with a commendation from Salisbury Civic Society Conservation Awards Scheme 2018.  It was a challenging project but one we’re pleased to be associated with.”

The work, from foundations to steel framework, through to the installation of benches and cladding, was completed on time and within budget.  For more information on the project, click here.

Christmas comes early with seven new PureGym fit-outs

At hebs Group we are proud of our ongoing work with PureGym to deliver new gym fit-outs for the fast-growing fitness brand.

We have built up a great level of trust to become a contractor in PureGym’s framework, which also saw us awarded the contract to fit out the 200th PureGym located in Brighton.

But the brand shows no signs of stopping its rapid growth and, in December 2018, no fewer than seven new PureGym locations opened their doors with facilities fitted by hebs Group.

With these new locations distributed nationwide, most of the population of England are within fairly close reach – testament to PureGym’s ambition to open in places where it is most convenient for the local community.

The seven new openings in December 2018 include:

  • Birmingham Beaufort Park
  • Bournemouth
  • Bristol Harbourside
  • Gateshead
  • London Borough
  • London Waterloo
  • Portsmouth

With our deep understanding of the unique nature of the leisure fit-out market – premises that serve a very practical purpose, yet also attract repeat custom in a comfortable and luxurious environment – we are pleased to see PureGym continue to go from strength to strength.


Happy clients, happy Christmas

As 2018 draws to a close, the true bellwether of how well we have done this year is in our clients’ satisfaction and the feedback and testimonials they provide us with.

Jonathan Graley, project manager for PureGym, had some glowing words for hebs Group that you may have already seen us share on our social media channels – you can find us on Facebook and on Twitter.

He said: “Thanks to everyone in hebs Group for all their hard work and effort in making 2018 such a useful year for PureGym. Looking forward to working with hebs Group again in 2019.”

We are also looking forward to continuing this great partnership and fitting out gym facilities in even more areas up and down the UK to the highest of standards.

How trenchless technology is transforming UK maintenance services

A wide range of UK maintenance services and new infrastructure installations, from water pipes and drainage to high-speed fibre optic networks and connecting green energy farms to the grid, are benefiting from trenchless technology.

Matthew Izzard, chairman of the UK Society of Trenchless Technology, told the Polish publication Trenchless Engineering that Britain is seeing strong demand for trenchless technology as part of attempts to cut down on water leakage and to install more fibre optics and new utilities.

“We are also seeing drivers such as the environment and reduced public disruption in cities, as well as technological advances in the equipment and design making jobs that were not possible to use no-dig on in the past now becoming influencers,” he added.


The importance of using trenchless technology experts

Mr Izzard listed some of the priorities of using trenchless technology – including the twin desires for safe and competent trenchless technology installations.

“It is important that the operators using the equipment do so in a safe environment and have been suitably trained for the application they are using,” he explained.

Safety training and expertise is backed up by the right documents and permissions to work on the proposed job site – including any necessary permits, conditions of acceptability, and permission to close roads if required.

At hebs Group we have considerable expertise in no-dig installations and maintenance, as our hebs Trenchless Solutions team has been providing UK maintenance services using trenchless technology since this modern method was in its infancy.

We also make sure to keep pace with the introduction of new trenchless technologies like cured in place pipe, or CIPP, LED-activated patch repair systems and laser-guided auger boring tools that can allow us to replace broken and burst pipelines in place.
